*You* choose the key, so you can do what you want :-)

There is not "highest" key value, as key is a string. But as Gambas 
automatically convert numbers into strings when needed, you can use a global 
variable to store a numeric value that you increment each time you add an 
item, and that you use as a key:

INC MyCounter
MyListView.Add(MyCounter, "text", ... )
